Have you ever wondered why Google's logo contains different colour combinations? Some say it has a logical and mathematical reasoning behind it whereas others say that it might just be out of randomness. Google revised its logo in 2015 with slight modifications from time to time since 1999. Let us look at the reasons why they probably chose two blue, two red and only one green and yellow colour. Breaking a regular colour pattern shows that Google doesn't follow the rules According to Ruth Kedar, there were a lot of different colour iterations. So they ended up with the primary colours, but instead of having the pattern go in order, they put a secondary colour on the L, which shows that Google doesn't follow the rules.

They combined the primary colours of paint and light, with a little aesthetic reasoning

Red, yellow and blue are the primary colours when considering paint.

Red, green and blue are the primary colours when considering light.

So it would be logical to combine these two to get

G = blue

o = red

o = yellow

g = blue

l = green

e = red

As for the order, it's possible that it was just for aesthetic reasons and to avoid starting with red.

Colours of the logo are reminiscent of the first Google server built from Lego bricks

Google's first server rack was built from Lego bricks, as the team considered it a more cost-efficient (and expandable) way to secure ten 4GB hard drives. The colours included in it were red, yellow, blue and green, same as the logo.
